STREET-CAR HEATER.

SPECIFICATION forming part of Letters Patent No. 431,947, dated July 8, 1890.

Application filed January 12, 1889. I Serial No. 296,155 (No model.)

To all whom it may concern.-

Be it known that I, HOSEA WV. LIBBEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Street-OarHeaters, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to produce a cheap, simple, and efficient apparatus for heating street-cars; and the invention consists of a systemof pipes and boilers whereby the car is heated by hot water, as hereinafter fully described, and pointed out in the claim.

Referring to the accompanying drawings, Figure 1 represents a horizontal section of a street-car, showing my system of heating applied thereto. Fig. 2 is a vertical section taken on line a: a: of Fig. 1. Fig. 3 is a vertical section taken on line 3 y of Fig. 1. Fig. i is a vertical transverse section of one of the boilers and water-supply reservoir; and Fig, 5 is a longitudinal vertical section of the same.

A represents the car, and B B the platforms.

Beneath each of the seats, and preferably in the center of the length of the car, are secured. saddle-shaped boilers O, on the top of which are secured water-reservoirs D. Each reservoiris connected with theboilerbeneath it by a pipe E, provided with a stop-cock e, as shown. (See Fig. 4:.) The tops of the reservoirs are each provided with a cap or cover (Z, by which they are filled, a small opening being formed in the frame-work of the seat to allow of access to the same, which opening may also be closed by a cover.

The boilers are heated by means of lamps F, which can be easily placed under the boilers or removed therefrom when it is desired to trim them.

To the upper part of each boiler is connected a delivery-pipe G, which passes to the end of the car, thence across the car to the opposite side, and thence along the car and back again just in front of the seat. The pipe then passes through the floor and out under the platform and beneath a grating H, upon which the driver stands. The pipe then passes back up into the car under the seat and to the lower part of the boiler on the side opposite from which it started. The pipes under the platform are inclosed within a casing, thereby preventing them from being so quickly chilled. It will be seen that by this arrangement the heated Water does not return directly to the boiler from which it started, but to the boiler on the opposite side of the car, thus keeping up a constant circulation through both boilers and the pipes. By the employment of two boilers the circulation is greatly enhanced, the car can be heated very quickly, and when sufficiently hot the lamps under one of the boilers may, if desired, be turned down or extinguished.

The cock 6 in pipe E may be left open, so as to keep the boiler always full, orit may be opened periodically by the conductor, as may be desired.

The pipes G in the car are covered by a grating J, a portion only of which is shown on one side in Fig. 1, so that the pipes may be clearly seen. These gratings, being only about the thickness of the pipes above the floor of the car, form a rest for the feet of the passengers, and I prefer to arrange a grating in front of the boilers, thereby preventing the clothes of the passengers from coming in contact therewith. By this 0011- struction of heaterthe car is made comfortably warm, and a foot-warmer for both the driver and conductor is provided at a very small cost, while the seating capacity of the car is not interfered with. i

What I claim as my invention is- The improved hot-water street-car heater, consisting of the lamps placed under the seats on opposite sides of the car, the inverted-U- shaped boilers fitting over the said lamps, the reservoirs supported by said boilers, the pipes connecting said reservoirs with their respect ive boilers and provided with stop-cocks, two series of pipes connecting said boilers, each of said pipes extending from one of the boilers under the seat to the end of the car, thence across the end of the car to the opposite side of the same, and thence in parallel branches the entire length of the car in front of the car-seat, thence through the floor of the car and under the platform, thence to the boiler opposite the one from which it started, the name to this specification, in the presence of casings surrounding the pipes below the plattwo subscribing witnesses, on this 31st day of forms, the gratings in the platforms above December, A. D. 1888.

the pipes, and the gratings within the ear cov- I-IOSEA XV. LIBBEY. 5 ering the longitudinal portions of the'pipes Witnesses:
